I run a local Fire/EMS scanner feed for my county so people can listen in without a scanner or SDR of their own. It uses a bunch of directional antennas in the attic for best reception (I can't put up a giant mast antenna) connected to a bunch of Nooelec rtl-sdr dongles.
Unlike a traditional scanner which only monitors one frequency at a time, if two things are happening simultaneously then you hear them both. This would be annoying or unlistenable in a busier area, but in my area it works fine.
